Adapting the iPhone for Insect Photography

Polistes dominula, the European Paper Wasp

captured with an iPhone

As an insect guy, the first question I ask about any camera is: Can I shoot bugs with it?

To my great disappointment, the answer for most cell phones is no. Cell phone cameras are normally fixed to focus at distances useful for party pictures and street shots. Fixed-focus simplifies the mechanics of the onboard camera, but it also makes close-ups of small subjects impossible. Even Apple's iPhone 3GS- which has variable focus- doesn't focus quite closely enough do anything but the largest insects. So when an aphid plague unexpectedly hits town, to name one real-life example, I have to go home and haul out my camera bag. No easy snaps.

An unmodified Apple iPhone 3G depicts the same wasp shown at the top of the post like this:

As you can see, the plane of focus falls behind this barely-visible insect. That's no good.

There's a simple solution. A magnifying lens placed over the onboard lens will move the focus point close to the camera. With an insect sitting nearly on top of a small lens, the resulting image is magnified to impressive size. The home-made rig looks like this:

I used a $20 lens and some masking tape, but any hand-lens should do. This arrangement allows the iPhone to cozy right up for some intimate bug portraits. I've posted a sampling below:

Given the low resolution of the iPhone sensor, I won't be making posters out of these images anytime soon. But they're fine for blog posts or powerpoint presentations. For a $20 hack, I'm not complaining.

I did! It was an origami microscope, with a single simple lens added. Here's what it looks like: It's called a Foldscope, and I got it as part of a beta test program. It's a bit like the original Leeuwenhoek microscope, which you held up to your eye to see a magnified image. The differences are…

The P. dominula is awesome!

Lovely images, especially the wasp.

Quick. Apply for patent for a plastic shoe, an existing case perhaps, that has been modified to hold the appropriate standard lens type to allow close shots. Make the lens mount such that the lens can be changed. Sell the shoe and a small selection of lenses together.

Put out a 'pro' version that allows better and wider selection of lenses and filters to be used.

IMHO there is an large potential market for attachments to an I-phone to allow better photography. Not just for macro shots but wide angle shots. Perhaps even specialty photography.

Well I'll be dipped! Can't wait to try this out.

I'm with Art!

I once heard a photographer say "the best camera is the camera you have with you"--for me, more and more, that's the camera in my phone.

I'd buy a case that had a set of, say, 4 lenses in a heartbeat. If they were set in a circle that you could flip through--like those old viewers that had a series of scenes of vacation spots . . . A close-up, a zoom, a wide-angle and a blank would be a nice set. Please let me know when they are available to order.

Nice! This almost makes me wish I had an iPhone. For anyone interested, you can probably find cheaper lenses too. Old binoculars have some handy lenses in the eyepieces, as do some of the cheap telescope lenses. Some camera stores also have/had a bin of lenses you can rummage through and find the magnifying ones that aren't chipped or damaged. Depending on what you grab they will run you maybe a dollar to completely free. Of course, that was before the digital camera era so perhaps those bins of discarded lenses aren't as common now(?).

I used old binocular lenses and my K-1000 Pentax camera's 50mm lens to make a macrolens. Later I also made a sliding focus telephoto lens, and a sliding macrolens, so I could control the amount of magnification (total cost was $15 for the adapter ring, originally used for attaching my camera to my telescope for astrophotography, and the sliding tube was just two different sized cardboard tubes from paper towel dispensers).

Adapting, modifying 'toys' is a great deal of fun.

[b]Too late, someone already came up with the idea:[/b]

See what happens when they use mind reading satellites and have a time machine. LOL.

Looks like they got the basic idea but blew the implementation. I was thinking something a bit more compact and made out of durable materials. I hate to see a good idea poorly carried out.

Fantastic! Now, if we could only teach this trick to certain contributors to Bugguide. Some of their cameras are slightly better than an I-Phone but the results are deplorable. Sigh!

Excellent shots. The iPhone is pretty sweet ... but this makes it even better. It's cool what a single lens can do to make the camera way more useful. (At the risk of sounding cheesy, this should be called the "bug-eyed iPhone.")

Seems to me you don't need an iphone for this - just a cell phone with a camera. Might even work better on cell phones with better cameras.

OMFG, that is brilliant. Betcha I can make these work on my Android.

I am a high school science teacher, and we routinely use cell phones to take micrographs, especially those of gram staining. you need to adjust the focal point manually (trial and error sometimes) but the hand lens may make that easier.

Funny you should say that:

Wow, this is great, thank you every one for such great ideas, I will put them to work here in Alaska. The flat taped on lens show by Alex would be the coolest iPhone cover, I would call it the iBug.
